Also, over the last 2-3 months or so, I'd guess that about 50% of the time I go to the website it's down. Granted, I don't go daily, so I'm guessing that part of this is just awesome timing on my part, but my general feeling is that this is becoming a more frequent occurrence. Is it just me?

I can't say for sure. But I think there was a github outage that caused this. As for the site being down, I'm probably looking at examples or the gallery 3x a day and haven't noticed it being down once. Who knows?
